I found the coolest Nudibrach in our tank today. I was breaking apart a good sized rock that was literally infested with aiptasia. We've never had those buggers before, but must have got one in at one point or another and WHAM!! Aiptasia city on this one rock. This rock was past kalkwasser or any other complete elimination cures, so I broke the rock in two since it was going in the pot for a boil off. I noticed this spotted fleshy piece sticking out of a good sized hole. I gently pulled him out (gloved hand of course), and was shocked when it kept coming and coming out of the rock. Finally got the whole fella out of there and started looking him over. I do believe he's a nudibranch, but he's not like any I've seen in the LFS. So, he smiled for the camera for you guys,:p and hopefully you can give me some more info on him. All my zoanthids that used to be in that tank disappeared over time and I'm wondering if he was the culprit. Anyway, he has a nice home in a different tank where there's nothing he can harm, and nothing that can harm him either. Here's the pics! Thanks in advance!
